Infinity REF1000S 10″ Mount Subwoofer

Description

Overview

The Infinity REF1000S is a 10-inch shallow-mount subwoofer from Infinity’s Reference Series. It is designed to give a good sub-bass punch in installations where space is limited (tight boxes, compact trunks, shallow mounting depth). It also has a Selectable Smart Impedance (SSI) feature allowing you to switch the nominal impedance between 2 Ω or 4 Ω to match different amplifiers or wiring setups. woofersetc.com+4th.infinityspeakers.com+4sonicelectronix.com+4

Features

• Selectable Smart Impedance (SSI): You can switch between 2 Ω or 4 Ω nominal impedance so the sub can match with different amplifiers or wiring setups. Crutchfield+2infinityspeakers.com+2

• Shallow-Mount Design: Reduced mounting depth to make it easier to install in tight spaces without sacrificing too much performance. sonicelectronix.com+2th.infinityspeakers.com+2

• Durable Construction: Polypropylene cone + large rubber surround, single stacked magnet, designed for automotive reliability. sonicelectronix.com+1

Performance & Trade-Offs

What this sub does well, and what limitations to expect:

Pros:

• Good low end for a 10-inch shallow sub, especially when paired with the right enclosure.

• Flexibility in matching to amplifiers thanks to its SSI switch.

• Relatively high peak power (800 W) for short bursts without distortion.

• Shallow depth helps in tight installs (small trunk, under-seat, behind-rear seats, etc.).

Cons / Things to Watch:

• Although the response goes down to ~35 Hz, you won’t get the extremely deep bass (“felt” bass) of larger 12- or 15-inch subs. If you want rumble down in the 20-30 Hz region strongly, a larger or more powerful sub might be better.

• Sensitivity is moderate (89 dB) — you’ll need enough power from the amplifier to drive it well. Switching to 2 Ω helps with more current draw but you need a capable amp.

• The impedance switch is physical and located on the back of the sub; you may need to remove the sub or access the back to change. Be careful when installing so that you don’t damage that component. Some user reviews mention this. sonicelectronix.com

• Ported enclosures usually trade off low-frequency extension and tightness versus output in mid bass; for really clean bass and less distortion, sealed is safer.
